ALBERT S. NEWTON, OF PROVIDENCE, RHODE ISLAND.

WASTE-TRAP.

Application filed March 1,

To all whom it may concern:

Be it known that I, ALBERT S. Nnw'roN, a citizen of the United States,residing at Providence, in the county of Providence and State of RhodeIsland, have invented certain new and useful Improvements in WVaste-Traps, of which the following is a specification.

My invention relates to waste traps and has for its primary objects theutilization of the waste water in rescaling, to efficiently guide thewater to the upper baffle plate, and by a means which will notaccumulate grease; and to attain these ends in a structure of increasedsimplicity, and efficiency.

My invention, therefore, consists in the means for attaining the endshereinabove set forth.

In the accompanying drawings which form a part of this specification,

Figure 1 is a central vertical section of my trap,

Fig. 2, a section of the of Fig. 1, and

Fig. 3, a vertical section of a modification.

Similar reference numerals indicate simisame on line a, w,

. lar parts throughout the drawings.

The body of my trap consists in the present instance of a substantiallycylindrical side wall 4 having a retracted rounded upper portion 5merging in an upwardly and outwardly directed neck or pipe 6 having athreaded connection 8 with a tube 9 which together with the neckconstitutes the outlet of the trap.

The lower end of the body is open and has a thread 11 engageable with anexternal thread 12 on a disk 13 providedwith a peripheral extension 14adapted to abut against the body. The bottom face of the disk has asquared operating projection 16, and fast in the upper face of the diskis a post having a solid lower portion 18 and a tubular upper portion 19provided with series of staggered perforations 20 in its wall 21 openinginto its bore 22. The wall 21 at its top expands to form an integraloutwardly and downwardly flaring abutment 24 or baffle plate forming anannular space.

Near its bottom the wall or body 4 is provided with a hollow projection26 extending outwardly and upwardly, having a threaded connection as at27 with a pipe 28, which combined with the extension constitutes the ilet of the trig Bel w t e be we mem er 2 nte ral h Specification ofLetters Patent.

the wall 4 is a downwardly inclined annular flange or deflecting plate30.

The water enters through the inlet and leaves the trap through theoutlet. In its course it is by the portion 30 so deflected that aportion thereof is impeded and thrown downwardly by the plate 24, whilesome of the remainder passes through the outlet, and the remainder fallsdown into the tubular part of the baflie plate and post, whence itpasses out through the perforations and assists to reseal the trap.

The grease is carried by the top of the water. The upper surface of thewater as soon as it reaches the lower edge of plate 24 cannot rise anyhigher therein because of the air in the annular space. Hence the greasecannot lodge in such space. The same is true of the downwardly directeddeflecting pate 30, which also forms an inclosed annular chamber.

If preferred the body 4 need not be cylindrical throughout its length. Amore economic form of body construction consists, as shown in Fig. 3, ofa lower cylindrical portion 32 of less diameter than the body 4 having aswelled upper portion 34 around the baffle plate.

I claim 1. In a waste trap, a body, an inlet pipe near the bottom of thebody, an outlet pipe in the upper portion of the body, and a post fastto the bottom of the body comprising a solid lower portion, a tubularupper portion provided with perforations, and an open baffle upon thetop of the tubular portion between the inlet pipe and outlet pipe.

2. In a waste trap, a body provided with a contracted upper portion, andwith a contracted intermediate-portion, an outlet pipe in the contractedupper portion, an inlet pipe in the lower portion of the body, avertical post fast to the bottom of the body, and a baflie plate on thepost intermediate the retracted portions.

3. In a waste trap, a'body, an inlet pipe near the bottom of the body,an outlet pipe in the upper portion of the body, a post on the bottom ofthe body, a baffle on the post between the inlet pipe and outlet pipe,and a downwardly inclined plate on the body below the baflie plate.

In testimony whereof I have afiixed my signature.
